   align-items:start is what keeps the inputs on a row level with one
   another: the labels are all a single line, so aligning the tops aligns
   the boxes, and an error message — which can run to two lines — then
   hangs below without shifting its neighbours. (Bottom alignment was
   tried first and does the opposite: one long error lifts its own input
   out of line with the rest of the row.) Keep new labels short. */
